Actionscript - 從基類調用子類構造函數

Question

我想從靜態超類方法內部創建一個子類的實例。這裏有一個例子：

class Base 
{ 
    public static function createSubclassInstance() 
    { 
     //What do I do here? 
     return new this.getSubclassType(); 
    } 
} 

class Sub extends Base 
{ 
} 

我想通過調用創建一個新的Sub實例：

var s:Sub = Sub.createSubclassInstance(); 

Answer 1

static properties aren't inherited
